Matrix transform due to reorder of the equation row number, for AX=b

Hi,
I'd like to solve equation AX=b, e.g., [a11, a12, a13; a21, a22, a23; a31, a32, a33]*{x1, x2, x3}'={b1,b2,b3}'
However, I'd like to reorder X vector by {x2, x1, x3}', so is there any matlab code can do the row and column transform for matrix A?
Thanks.

I have to reorder elements of vector x and b, so rows and columns of A should be switched.

A= A(:,[2 1 3])
b=b([2 1 3])

Hi Azzi, how A should be changed if elements of b should also be switched as b=b([2 1 3])
